[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] See also Figure 1 The utility model provides an information transmission device based on a smart fire protection system, which includes an intelligent early warning unit and a controller. The intelligent early warning unit is connected to a LORA gateway, and the LORA gateway receives data information transmitted by the intelligent early warning unit through a wireless communication module. The LORA gateway is connected to a cloud platform module; it also includes an information transmission module, which receives data information transmitted by the LORA gateway through an Ethernet communication module and transmits it to the controller. The controller receives data information analyzed and processed by the information transmission module.

[0023] The utility model serves as a communication medium for conversion between wired and wireless fire-fighting systems, realizing the combination of wireless communication and wired communication of the intelligent fire-fighting system. The cloud platform module and the information transmission module are respectively the server ends of the LORA gateway. The information transmission module organizes the data information of the wireless fire-fighting equipment transmitted by the LORA gateway and sends it to the controller, and issues the command through the controller. When the wired and wireless fire-fighting systems are used in the same area, the equipment data information received by the two systems is equal and unified, thereby reducing the work difficulty of the staff and reducing management costs.

[0024] In this embodiment, the intelligent early warning unit includes a wireless smoke alarm. At least one wireless smoke alarm is provided. Alternatively, several wireless smoke alarms may be connected in series and networked according to the requirements of the location where the intelligent fire protection system is used.

[0025] Specifically, wireless smoke sensors are used to monitor fire areas and monitor the smoke data of the environment in the area in real time. The wireless smoke sensor is connected to the Lora gateway through the Lora wireless communication device, and can transmit the fire alarm information or fault information of the body in the monitored area to the Lora gateway.

[0026] Furthermore, the intelligent warning unit can also use sound and light warning equipment, combustible gas warning equipment or other fire warning equipment. At the same time, the specific setting quantity and series and parallel connection methods can be selected according to the actual use requirements of the fire protection system. One or more of them can be selected for setting. At the same time, the intelligent warning unit is equipped with at least one.

[0027] In this embodiment, the LORA gateway receives data information transmitted by the wireless smoke sensor through the wireless communication module in a wireless communication manner. A network server is provided inside the LORA gateway, and an application server is connected to the network server. The LORA gateway continuously receives data sent by the wireless smoke sensor and transmits it to the network server. The network server will organize the data and send it to the application server. The application server includes a cloud platform module and an information transmission module. The cloud platform module and the information transmission module are the two service ends of the LORA gateway respectively. The LORA gateway can act as a client to set the IP address of the application server to be connected and the communication protocol between the application server and the application server in the network server, and analyze, process and transmit the data information according to the communication protocol.

[0028] Specifically, the LoRa gateway uses the MQTT data transmission protocol to transmit network data. The LoRa gateway sends a protocol connection request and the information transmission module responds.

[0029] Furthermore, a wireless response device is connected to the cloud platform module, and a wired response device is connected to the controller. The cloud platform module includes a cloud platform. After receiving the gateway data signal, the cloud platform sends a response instruction to the gateway, organizes the data as needed, and transmits the data to the wireless response device, thereby realizing wireless communication transmission of the fire protection system.

[0030] In this embodiment, the controller is a fire alarm controller, which is used to receive data information analyzed and processed by the information transmission module and send the information to other wired response devices for fire response.

[0031] like Figure 2 As shown, the information transmission module includes an MCU, a power module, a CAN interface, and an Ethernet interface. The information transmission module is connected to the LoRa gateway through the Ethernet interface, and the information transmission module is connected to the controller through the CAN interface.

[0032] In this embodiment, the information transmission module serves as one of the service terminals of the LoRa gateway and can receive all wireless firefighting equipment information passing through the LoRa gateway, making the information transmission module a communication medium for conversion between wired and wireless, thereby realizing the integration of wired firefighting systems with wireless firefighting systems. After power-on, it immediately enters the listening state, waiting for the connection of the LoRa gateway; after the connection is successful, it can receive data information from the LoRa gateway and also needs to respond to the reply command and send it to the gateway.

[0033] Specifically, the information transmission module receives the data information transmitted by the LoRa gateway through Ethernet communication. The information transmission module is connected to the controller through the CAN line. The information transmission module converts the received data information into the CAN protocol and sends it to the controller. Then the controller sends the data instructions to other wired response devices.

[0034] In this embodiment, the information transmission module is configured as the gateway's server through a software program and is constantly in a listening state, monitoring the gateway's connection information to establish communication with the LoRa gateway. After receiving the gateway's data information, the information transmission device converts the data into CAN protocol data according to the program's protocol layer and sends it to the fire alarm controller via the CAN line. If a fire alarm is received, the fire alarm controller directly transmits the fire alarm information to the sound and light, input and output modules, etc., and activates wired devices such as fire hydrants to notify people of the fire alarm information and prevent and control the fire.

[0035] In this embodiment, the information transmission module also includes a USB interface and a status indicator light. The USB interface is used to update software programs, database information, etc. via a USB flash drive. The status indicator light includes a running indicator light, a CAN indicator light, and an Ethernet indicator light.

[0036] Specifically, the power module includes a 24V power interface and a 12V power interface. The information transmission module is connected to the 24V power interface through a power cord to power it. After the device is powered on, the running indicator light is always flashing, indicating that the internal program of the MCU is running normally. If it is always on, it means that there is a problem with the information transmission device; the Ethernet interface is used to connect to the LORA gateway. After the connection is successful, the Ethernet indicator light will be always on. If the connection is abnormal or there is a fault, it will be always off. When the indicator light flashes, it means that data is being transmitted; the CAN interface is used to connect to the controller. When the connection is normal, the CAN indicator light is always off. If there is a connection abnormality or fault, the indicator light is always on. When there is data transmission, the indicator light flashes.

[0037] Furthermore, as a preferred embodiment of the present invention, the MCU of the information transmission module adopts an STM32F407VGT6 microcontroller, and a software program is used to analyze and process the data information and transmit it to the controller.

[0038] The fire monitoring communication flow chart of the information transmission device of the embodiment of the utility model is as follows Figure 3 The specific workflow principle is as follows:

[0039] First, after the information transmission module is powered on, the program will initialize the Ethernet. After confirming that the Ethernet communication line is connected, it will enter the TCP connection process, create the IP address of the information transmission device, bind it, enter the listening state, and wait for the TCP connection information of the gateway. If the connection information of the gateway is received and a three-way handshake is established, it means that the connection is successful. If no connection information from the gateway is received, the information transmission device will remain in the listening state, waiting for the connection from the gateway.

[0040] Secondly, after the information transmission module successfully establishes a TCP connection with the LORA gateway, the gateway will send a connection request of the MQTT protocol according to the data transmission protocol. The information transmission device will immediately respond to the connection after receiving the request. The gateway receives the response, which means that the data transmission of the MQTT protocol has been successfully established at this time; if there is no other information transmission in the gateway, the gateway and the information transmission module maintain normal communication connection through heartbeat information.

[0041] If the wireless smoke sensor detects that the smoke information in the environment has reached the threshold, it will immediately send the fire alarm information to the LoRa gateway through LoRa communication. The gateway will convert the address, event and other information of the received wireless smoke sensor into MQTT protocol data. Since the gateway and the information transmission device have established normal communication, the fire alarm data can be directly sent to the information transmission module through Ethernet. At this time, the information transmission module will convert the MQTT protocol data into CAN communication data again and send it to the controller through the CAN data line.

[0042] The controller transmits the fire alarm information to wired devices such as audio and video, input and output modules, and the data information sent by the wireless smoke sensor can be transmitted to wired audio and video devices, thereby converting the wireless communication mode to the wired communication mode. If there is a cloud platform server in the system, the LORA gateway can also transmit the fire alarm information of the wireless smoke sensor to the cloud platform at the same time. At this time, the data information received by the cloud platform and the fire alarm controller are consistent, realizing the unification of wired and wireless communication data, thereby reducing management difficulty and cost.

[0043] The utility model provides an information transmission device based on a smart fire protection system, which is easy to operate. This device serves as a communication medium for conversion between wired and wireless fire protection systems, realizing a smart fire protection system that combines wireless communication with wired communication. The cloud platform and the information transmission module are respectively the server ends of the LORA gateway. The wireless device transmits fire alarm, fault and other information to the LORA gateway through wireless communication. The gateway, as the client, organizes and converts the data information into MQTT protocol data, which can be sent to the cloud platform server through wireless communication, or transmitted to the information transmission module through Ethernet communication. The information transmission module organizes and converts the data information of the wireless fire protection equipment transmitted by the LORA gateway into CAN protocol data and sends it to the controller. The controller then sends the command or data to other wired fire protection equipment, and vice versa.

[0044] In addition, the information transmission module serves as the server end of the LORA gateway and can receive all wireless fire-fighting equipment information passing through the LORA gateway, making the information transmission device a communication medium for conversion between wired and wireless, thereby realizing the combination of wired fire-fighting systems and wireless fire-fighting systems. When wired and wireless fire-fighting systems are used in the same area, the equipment data information received by the two systems is equal and unified, which reduces the work difficulty of staff and reduces management costs.
